WEAVING SHUTTLE.

Application filed February 4, 1922. Serial No. 534,148.

'To aZZ whom it may concern.

Be it known that I, ALoIs KLERX, a citizen of the United States of America, residing at Detroit, in the" county of Wayne and State of Michigan, have invented certain new and useful Improvements in Weaving I Shiittles, of which the following is a specification, reference being had therein to the accompanying drawings.

' This invention relates to devices known as weaving shuttles for carrying the'b obbin and the object of the invention is to provide a very durable device for the purpose which will also be light in construction and may -be readily manufactured from metal.

With the above and other ends inv view,

the invention consists inthe matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure 1 is a plan view of a shuttle illustrative of the invention;

Fig. 2 is a side elevation of the same with an end portion thereof in longitudinal sec tion;

Fig. 3 is a perspective view of the forward end of the shuttle in transverse section substantially upon the line 3-3 of Fi 2;

Fig. dis a sectional detail Illltifil illustrative of the threading device, and I Fig. 5 is a transverse section substantially upon the line 55 of Fig. 2.

Shuttles are commonly constru'ctedwith a wooden body and in order to give thenceessary wearing qualities this body must be comparatively heavy. and formed of a close grained wood, thus making the body heavy to handle and operate.

In the present construction the body 1 is cast or otherwise formed from' a suitable metal such as an aluminum alloy, making it light because of the thinness of the walls and giving it durability. Each end' of the body is preferably tapered, as at 2, and formed with an end wall 3 having a face forming a seat for a steel point 4. This steel point is secured in place by a screw-threaded stud 5 on the point extending through an opening in the wall 3 and held in place by a nut or other suitable means. The hollow body is formed in its upper side with a longitudinal slot 6 through which a thread bobbin, indicated in dotted lines at 7, may be inserted. The usual bobbin holding spindle 8 is pivoted at 9 within the rear end of the body so that it may swing upwardly through the opening 6 and permit the bobbin to be slipped thereon. The usual holding fingers 10 are provided adjacent the pivot 9. to receive one end of the bobbin and hold it in lace upon the spindle after the spindle has been swung downwardly into the shuttle A followerblock 11 is mounted upon a stud 12 with a spring 13 sleeved upon the stud between an abutment or hearing 14 and the block to normall hold the block pressed toward the stud o the spindle and thus hold the spindle in theposition to which it is turned upon its pivot 9. The bobbin is thus held upon the spindle free to turn thereon .and in operative position within the hollow body. Any suitable tension device which is indicated as a whole by the numeral 15 is mounted in the forward end of the body and the thread 16 is led from the end ofthe bobbin' through this tension device. From the tension device the thread is threaded through an elongated opening 17 in one side of the body in such a manner that it may readily be threaded into this opening and cannot escape therefrom laterally. To prevent friction upon the thread so that it will not be worn as it is pulled from the bobbin or become out or broken by passing around sharp corners, a pair of rods 18 is mounted vertically within the hollow bod adjacent each end of the opening 17, an these rods are preferably made of glass or other very hard smooth material whlch will not be cut or worn away by the thread and will rovide a smooth surface in contact with w 'ich the thread is pulled through the thread opening upon reciprocation of the shuttle. A suitable groove 19 is formed in the side of the body within which the thread isadapted to he as the shuttle is reciprocated in its guides and prevent the 11 thread from becoming entangled or worn. Obviously changes may be made in the 50 lhe opening 17 is located in the forward end of this groove 19 and in order to permit the ready insertion of the thread into this opening without the necessity of threading the end of the thread through the open-- ing, a slot 20 is formed in the wall of the body extending from the opening 6 in the top thereof and opening into the rear end of the threading opening 17 the slot being inclined in the side wall of the body and forming an angularlyshaped prong 21 intermediate the ends of the opening 17 Where the slot cuts through into the opening. The point of this prong 21 is inbent to bring it close to the outer side of the guide rod 18 which is. positioned at the rear end of the opening 17 and therefore thethread 1 6 may he slipped laterally through the slot 20 and past the prong 21 into the opening 17 between the rods -18 without the necessity for threading the thread endwise through the opening and when in place within the opening it can not escape from the opening through the slot 20 by reason of the point of the prong lying adjacent the outer side of the rod 18 with the slot 20 extending upwardly in an inclined direction from the end of the opening 17. The thread is thus very quickly and readily threaded through the opening in-the side of the shuttle and held against esca e therefrom, at the same time being gui ed and guarded against being cut or worn by passing out through the opening between the glass the walls thereof may be thin and light, givingthe necessary strength and wearing qualities without adding to the weight over a body formed of wood and the friction of the body passing thron hits guides, in

operation, is reduced to t e minimum. By depressing the bottom wall of the body 'inwa'rdly, as at 22, and forming the depressed portion of the wall with a series of o nmgs 23, dust and dirt are ermitte to freely escape and afree circu ation of air through the shuttle, is permitted.

form and arrangement of parts without dearting from the spirit of the invention and do not therefore limit myself to the particular construction shown.

Having thus-fully described my invention. what I claim is 1. A shuttle comprising "a hollow metal body having an elongated thread opening in a side wall thereof with a slot in said wall opening into said elongated opening and forming an angular point at one side of the slot, guide means withinthe body extending across the slot adjacent said point to permit the threading of a thread into the elongated opening and prevent the escape of thread therefrom.

2. A shuttle comprising a hollow metal body having an elongated opening in one wall thereof with athreading slot extending into said elongated opening and through the top of the wall of the body, glass rods mounted in {the body at the inner side of the elongated opening adjacent each end thereof with the point of opening of the slot into said elongated opening opposite one of said rods to permit the free entrance of a thread into the elon ated openin and plermit its escape there rom throng the s 0t.

3. A shuttle comprising a hollow metal body having a longitudinal opening in its top wall and an elongated thread opening in its side wall with a slot connecting the top opening with one end of the elongated opening, a prongadjacent one side of the slot, a glass rod-mounted in the body adjacent one end of the elongated opening with the point of the prong adjacent said rod,

a second glass rod in the body adjacent the opposite end of the elongated opening, and a spindle inthe body adapted-to receive a bobbin. 7
